In the present work, we investigate the macro- and micromorphology and the phylogenetic position of the genera Australomussa and Parascolymia, two monotypic genera ascribed to the family Lobophylliidae. The molecular phylogeny of both genera was addressed using three markers, the partial mitochondrial COI gene and the nuclear histone H3 and the ribosomal ITS region. Based on molecular data, Australomussa and Parascolymia belong to the Lobophylliidae and they cluster together with the genera Lobophyllia and Symphyllia within the same clade. While A. rowleyensis and P. vitiensis are closely related based on the three gene regions examined, their macro and micromorphology suggest that these species are distinct, differing in several characters, such as continuity and thickness of the costosepta, the number of septa, septal tooth height, spacing, and shape, and the distribution and shape of granules. Thus, we revise the taxonomic status of the genus Australomussa as a junior synonym of Parascolymia. specialized CORAIL TAXONOMIE PHYLOGENIE ANATOMIE ANIMALE CARACTERE MORPHOLOGIQUE MICROSTRUCTURE ADN MARQUEUR GENETIQUE PACIFIQUE NOUVELLE CALEDONIE AUSTRALIE PAPOUASIE NOUVELLE GUINEE 034BIOINV05 83 3 195-215 2014 1383-4517 https://www.documentation.ird.fr/hor/fdi:010062877 1383-4517 [F B010062877] https://www.documentation.ird.fr/hor/fdi:010062877 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers14-09/010062877.pdf IRD - Base Horizon / Pleins textes 2014-09-23 2015-06-11 fdi:010062877 fre
